See if you have slap echo
chap your hands sharply and listen for tinny echo
I find corner treatment placements work best
Real Traps and GIK are great sources
back wall absorbtion
GIK does art panels with professional photographs via sites like photostock or your own higher rez image. I have 3 nice pieces
i also use stretched cloth / canvas artwork - works nice, just enough absorption. You can hang a lot of art with neutral sound influence
art.com has thousands of great works
too much sound treatment and your system can sound like mud.
All the best in your journey
